Thiophene was polymerized by means of UVirradiation using diphenyliodonium hexafluorophosphate as a photoinitiator. An initiation mechanism involving electron transfer from photochemically generated onium radical cations to thiophene was proposed. N-Ethoxy-2-methylpyridinium hexafluorophosphate and triphenylsulfonium hexafluorophosphate were also found to be effective in facilitating the polymerization of thiophene. Polymerization is accompanied with the film formation on the surface of the reaction tube. The photochemically obtained polymers were characterized by FT-IR, DSC, and SEM analyses and compared with those obtained by oxidative and electrochemical means. Electrical conductivities of the samples were measured by four-probe technique.

Crosslinked polymer gels for boron extraction derived from N-glucidol-N-methyl-2-hydroxypropyl methacrylate Bicak, N; Ozbelge, HO; Yılmaz, Levent; Senkal, BF (Wiley, 2000-03-24) Glycidyl methacrylate was reacted in 2-methyl pyrrolidone solution with N-methyl-D-glucamine (NMG) to produce N-D-glucidol, N-methyl-2-hydroxy propyl methacrylate (GMHP). The reaction proceeded exclusively via ring opening of the oxirane. The resulting vinyl monomer was a waxy product and soluble in water, ethanol, methanol, DMF, and NMP. Copolymerization of GMHP with N,N'-tetraallyl piperazinium dichloride by the inverse suspension method (water in oil), using a toluene/chloroform (3:1) mixture as continuo...
Benzotriazole and Benzodithiophene Containing Medium Band Gap Polymer for Bulk Heterojunction Polymer Solar Cell Applications UNAY, Hande; UNLU, Naime A.; HIZALAN, Gonul; HACIOGLU, Serife O.; Yildiz, Dilber Esra; Toppare, Levent Kamil; Çırpan, Ali (Wiley, 2015-02-15) An alternating donor-acceptor copolymer based on a benzotriazole and benzodithiophene was synthesized and selenophene was incorporated as -bridge. The photovoltaic and optical properties of polymer were studied. The copolymer showed medium band gap and dual absorption peaks in UV-Vis absorption spectra. Photovoltaic properties of P-SBTBDT were performed by conventional device structure. The OSC device based on polymer: PC71BM (1:1, w/w) exhibited the best PCE of 3.60% with a V-oc of 0.67 V, a J(sc) of 8.95 ...
Enzyme immobilization in a photosensitive conducting polymer bearing azobenzene in the main chain AK, METİN; Yildiz, Huseyin Bekir; Toppare, Levent Kamil (Springer Science and Business Media LLC, 2014-07-01) A new photosensitive and thermosensitive monomer, namely bis(4-(3-thienyl ethylene)-oxycarbonyl)diazobenzene (TDAZO), was synthesized. The photochemical and thermal cis-trans isomerization of the monomer has been investigated. The rate constants of the photoisomerization of TDAZO in ACN and DCM were 0.195 and 0.308 min(-1), respectively. For spectroelectrochemical investigation and enzyme immobilization application, TDAZO copolymerized with thiophene and pyrrole. Electrochemical and spectroelectrochemical p...
Stereoselective synthesis of optically active cyclopenta[c]pyrans and cyclopenta[c]furans by the intramolecular Pauson-Khand reaction Sezer, Serdar; ŞAHİN, Ertan; Tanyeli, Cihangir (Elsevier BV, 2010-03-16) An intramolecular Pauson-Khand reaction of enynes derived from homoallyl, homopropargyl, and allyl alcohols is described. 2-Heteroaryl-substituted homoallyl, homopropargyl, and allyl alcohols are easily and efficiently resolved through enzymatic resolution in high ee (91-99%) and with a known stereochemistry. Each enantiomerically enriched enyne derived from homoallyl and homopropargyl alcohols affords the conformationally most stable diastereomeric cyclopenta[c]pyran ring system as the sole product, wherea...
Synthesis of conducting block and graft copolymers with polyether segments Yagci, Y; Toppare, Levent Kamil (Wiley, 2000-07-01) Synthesis of block and graft copolymers containing polyether and conducting polypyrrole sequences were described. Pyrrole moieties were incorporated at the chain ends of polytetrahydrofuran and polysiloxane and at the side chains of polyethyl vinylether by ionic polymerization and appropriate chemical reactions. Subsequent electropolymerization with pyrrole through these moities yielded free standing films of the corresponding block and graft copolymers. The formation copolymers was evidenced by FTIR spectr...
